Attorney and Del Mar College Regent Guy Watts remained in the Nueces County Jail on sexual assault charges Tuesday night after his wife reported he assaulted her at their home.

Watts' wife, from whom he filed for divorce Friday, called police just before midnight Monday, and police arrested him early Tuesday at his home in the 4200 block of Ocean Drive. Kimberly Watts, 42, was taken to Corpus Christi Medical Center-Doctors Regional, but police didn't indicate her condition.

Reynaldo Pe&#241;a, Watts' attorney, called his client's arrest an injustice.

&quot;Mr. Watts has an impeccable record as an attorney, and does more for this city than any other person I know,&quot; he said

Judge J. Manuel Ba&#241;ales of the 105th District Court said at a hearing Tuesday that, as is standard in family violence cases, Watts, 66, would have to be held for 24 hours and would be able to post his $50,000 bond today.

Ba&#241;ales set an arraignment hearing for 8 a.m. Jan. 2 in the same court. He also ordered that Watts be given an HIV test and wear an electronic monitoring device. Court officials said these measures are standard in sexual assault cases.

When he was brought before Municipal Court Judge Margie Silva Flores on Tuesday afternoon for a separate, emergency protective order hearing, Watts said he didn't know what happened. The order was filed against him after his arrest.

Under the terms of the protective order, Watts is not permitted to return to his house and must stay away from his wife and stepchild. Watts said he planned to file a motion to vacate that order.

During the hearing, Watts said he went to bed at about 8 p.m. Monday so he could wake up early to jog the next morning. He said the next thing he knew, police were waking him up at about 11 p.m.

Watts filed for divorce Friday from his wife, and he has filed for divorce from her three prior times: in January 2005, August 2006 and August 2007, before withdrawing the paperwork, according to records from the district clerk.

Cmdr. David Torres said enough physical evidence was found at the Watts home after police arrived to make an arrest. However, he would not give specifics.

&quot;During the course of an investigation we pick up evidence, whether bedsheets or other,&quot; he said.

Torres also said Kimberly Watts was examined at the hospital for evidence of sexual assault.

Watts was elected to the Del Mar College Board of Regents District 4 position in 2001 and his term expires in November. He also served as a regent from 1988 to 1990 and 1992 to 1999. Watts ran unsuccessfully this year for the City Council District 4 seat and also applied to fill a vacant Corpus Christi Independent School District seat.

Del Mar College Board of Regents President Chris Adler referred comment to board attorney Augustin Rivera Jr., who said Tuesday it was premature for the board to take any action in response to Watts' arrest. The next board meeting is set for Jan. 29.

Although community college board policy guidelines set by the Texas Association of Community Colleges -- of which Del Mar College is a member -- state a trustee can be removed from a board if convicted of a felony or for misconduct, the association's policies act only as guidelines for member colleges.

Sexual assault is a second-degree felony, punishable by up to 20 years in prison and a $10,000 fine.
